IPC: B22D19/00
Filed: 1979-02-05
Abstract: PURPOSE: To improve producibility and crack resistance property by a method wherein casting cores are subjected to internal chill in such condition that they each enclose a closed space, and both ends of support pipes connected with the cores are subjected to aperture expanding treatment.  
     CONSTITUTION: A metallic support pipe 6 is fitted in both cylindrical portions 4c of a cocoon-shaped metallic casting core 4, to form a core body C. Such core bodies C are held in a mold in such a manner that their axes accord with the axis of a journal portion 1 or a crank pin portion 3, casting is conducted around the core bodies C. Thus, a crankshaft provided at its journal portion 1 and crank pin portion 3 with cocoon-shaped hollow spaces A capable of largely enhancing torsional strength as compared with solid structure is molded integrally. After casting, both end portions 6a of the pipes 6 are cut off, and the new pipe ends are subjected to aperture expanding treatment.

Filed: 1987-01-22
Abstract: PURPOSE:To stop the transmitting of a data in which an error is present by providing a data comparator which lets a storobing signal be outputted only when a data from a data buffer and that from an output gate are coincident with each other. CONSTITUTION:The data comparator 17 compares whether the data on a data output line 11 outputted from the data buffer 10 and the data on a data line 5 outputted from the output gate 3 are coincident with each other, and outputs a comparison output signal to a comparison output line 18. A strobing signal controller 19 outputs a strobing signal through a strobing control line 9 to a strobing output line 20 only at a time when said comparison output signal from the data comparator 17 represents an coincidence state. When a noncoincidence signal is outputted to the output line 18, a strobing signal through the strobing control line 9 is not transferred to the strobing output line 20.

Abstract: PURPOSE:To enable the processing speed-noise relation to be arbitrarily and easily set in accordance with the conditions of using site by arranging so that motor relation can be arbitrarily changed by switch setting. CONSTITUTION:When accelerating a motor 3.1 from reset state, the first data of an acceleration/deceleration table is set on a timer 3.5. The timer 3.5 counts down the set data and produces interruption when the count is equal to '0' to a CPU3. Upon reception of interruption, the CPU3.3 causes the stepping motor 3.1 to rotate by an angle equal to one step, sets the next phase data in a latch 3.2 and sets the second data in the timer 3.5. By sequentially reducing the data set on the timer 3.5, rotation of the motor 3.1 is accelerated. Motor control is started by a dip switch 3.6 by an acceleration table and it is selected to which number execution should be made so that the maximum speed of the motor 3.1 can be selected.
